Mac Login Keychain Cannot Be Found Error — What It Means & How to Fix It

Fix macOS 'login keychain cannot be found' error preventing saved passwords, certificates, and secure notes from being accessed. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: The login keychain (~/Library/Keychains/login.keychain-db) stores passwords, certificates, and encryption keys. If this file is deleted, corrupted, or its permissions change, macOS cannot access stored credentials. The error causes repeated password prompts for Wi-Fi, email, websites, and application-specific passwords. Time Machine does not back up the keychain file for security reasons, making corruption harder to recover from. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Keychain file was accidentally deleted or moved from ~/Library/Keychains/. File permissions on the keychain file were changed, preventing access. Password change (local or via Active Directory) without updating the keychain password. Disk corruption affecting the keychain database file. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Open Keychain Access app > Keychain Access menu > Preferences > Reset My Default Keychains. If that fails, create a new login keychain: security create-keychain -p '' ~/Library/Keychains/login.keychain-db. Make it the default: security default-keychain -s ~/Library/Keychains/login.keychain-db. After creating a new keychain, you will need to re-enter all saved passwords as they are in the old keychain. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
